International Classification:

H02P 6/16

US Classification:

31840012, 318432, 318434

Abstract:

A system and method for controlling any of a variety of permanent magnet motors includes normalizing motor parameters with respect to demagnetization current of a motor and developing a torque-per-current relationship using the normalized motor parameters at approximately maximum torque. Using the developed torque-per-current relationship, it is possible to control any of a variety of permanent magnet motors without the need for extensive configuration of a motor control unit for a specific motor.

H02P 1/46

US Classification:

318720, 318700, 31840001, 31840002

Abstract:

The invention includes a motor controller and method for controlling a permanent magnet motor. In accordance with one aspect of the present technique, a permanent magnet motor is controlled by, among other things, receiving a torque command, determining a normalized torque command by normalizing the torque command to a characteristic current of the motor, determining a normalized maximum available voltage, determining an inductance ratio of the motor, and determining a direct-axis current based upon the normalized torque command, the normalized maximum available voltage, and the inductance ratio of the motor.

Abstract:

A mounting system for a member to a support structure. The member includes ends and sides. A hinge may be attached to one of the ends of the member. Hinges may be attached to both ends along the same side of the member. The hinge may include an arm from which a tab extends. The ends may include securing means. The support structure includes a mounting aperture that is configured to interact with the hinge of the member. In some embodiments, the support structure may have multiple mounting apertures. The mounting aperture is configured to prevent the hinge of the member from disengaging from the support structure. In some embodiments, the mounting aperture is configured to pivotally retain the hinge of the member.

Abstract:

Retrofit systems for replacing the outdated components of an existing light fixture. The retrofit systems may utilize the previously installed housing of the existing light fixture. The retrofit systems include brackets that are positioned on the ends of the housing. The positioning of the brackets is based off of the ceiling, t-grid, or the bottom of the housing. Lamp sockets with associated lamps, an optional ballast tray with associated ballast, reflector(s), lamps, and a shielding mechanism are all mounted on, and their position in the housing dictated by, the mounting brackets. Thus, regardless of the depth of the housing, the lamps are positioned a uniform distance from the ceiling opening to create consistent light distribution. Moreover, because these components are not directly attached to the housing, their dimensions need not precisely match those of the housing. Rather, the retrofit system can be installed in housings of varying sizes and shapes.

International Classification:

H03K 5/00

US Classification:

31840013, 31840001, 318700

Abstract:

The present invention provides an improved current regulator for PWM based drives for electric motors. The invention provides compensation for the rotor position signal for delays introduced due to the PWM algorithm and for digital sampling present in such a drive. Current regulator commonly operate in a two-phase reference frame, requiring forward and reverse coordinate transformations between the physical current values and the two-phase reference frame variables. The present invention provides an improved compensation in the forward transformation by determining the phase lag between the commanded voltage reference and the output voltage reference and by further compensating the forward transformation for errors introduced due to sampling the current either at different sampling instances than the rotor position or at multiple sampling instances during a carrier period. Additionally, compensation during the reverse transformation is provided to compensate for errors introduced due to sampling the current and rotor position.

Abstract:

Described are strip lighting fixtures having a channel defined by a base plate and two side walls, end plates located at each end of the channel, and a channel cover that snap-fits onto the channel. The channel side walls include at least one gripper indentation that releasably engages with at least one tong hanger hook via a snap-fit connection to attach the strip fixture to a support structure. As examples, the tong hangers include hooker clips that connect the tong hanger to a support structure, and the channel cover is contoured to provide additional spacing or relief areas to avoid pinched wires when the channel cover is connected to the channel.
